Each device Fig-1118.4 an {enlarged elevational V Of a 10 comprises what may be designated as'a lower .fragmentary nature depicting the particular fOrlink 15 and companion upper link 16. The 105 mation of the jointed end of the companion links upper link is pivoted at its outer end as at 1'7 of one of the stay devices. to the cross brace 9. The corresponding end Figure 5 is a view of Figure 4 looking at it of the lower link 15 is pivoted as at 18 to the in a direction from left to right. metal strap 12. The adjacent or corresponding It is believed that so far as the general asinner ends of the links are pivoted together. 11'

This is shown better in Figure 4. Referring to this figure it will be observed that the inner end of the link 15 is directed at right angles or laterally as denoted at 19. At its free end it is provided with a stud 20 (see Figure 5) which serves not only as a stop element but also as a meansfor attaching a handle or hand grip 21 to said link 15. The link 16 alsohas its inner end bent laterally as indicated at 22 and pivotally connected as at 23 to the link 15 at'a point inwardly of the part 19. This allows the jointed end portions of the two links to swing into intersecting relationship and beyond dead center so as to provide a substantially automatic self sustaining stay means. otherwise when the two links are expanded to the sustaining position shown in Figure 2 the pivoted end of the link 16 swings across the corresponding bent end portion 19 of the link 15 and said link 16 rests against the stop pin or stud 20. To aid in the sensitivity and nicety of operation I provide coil springs 24 and 25 connected to the links 15 and 16 and the parts 9 and 12 respectively as shown in Figure 2. These springs exert a stress or pull upon the links to facilitate unfolding or opening of the links and as the links unfold and spread apart they exert an upward stress or thrust upon the bed spring to aid in lifting it. ever the bed spring is grasped at about the center by the attendant. It is lifted upwardly and the opposite edge portions fulcrum against the stop elements 14 as shown in Figure 2.

Assuming that the bed spring is inclined to 'the position shown in Figure 2 and it is dement thereof on alternate opposite sides of the.

bed frame permits the bed spring to be lifted up first on one side and then on the other to facilitate cleaning of the spring, cleaning of the bed frame and slats, if any, and the fioor therebeneath.

Having thus described my invention, what I claim as new is:

1. In a structure of the class described, a stay device comprising a pair of links, the inner end of one link being directed laterally and l provided with a stud constituting a stop element with the corresponding end of the remaining link being directed laterally and pivotally attached to said first named link, the two laterally extending portions projecting in the same diirection and the lateral part of said remaining link being pivoted to the other link an appreciable distance from the lateral part of said other link and the stud being engaged by a part of said remaining link when the linksare in "Iunfolded position, and means for connecting the outer ends of the links with a bed frame and bed spring respectively, together with a hand grip carried by said stud to facilitate operating the links.

Stated Initially how- 2. In a structure of the class described, a pair of links having their inner ends bent at right angles, the bent end of one link being pivoted to the other link an appreciable distance from the bent end of said other link, a stud on the bent end of said other link for engagement by the first link for limiting unfolding movement of the links, a cross member adapted to be supported by a part of a bed and to which the outer end of the stud carrying link is pivoted,

means for pivoting the outer end of the other link to a bed spring assembly, and a spring for connecting each link to the part to which the outer end of the link is pivoted.

3. In combination with a bed and its spring assembly, a pair of cross bars having their ends extending upwardly and the upper end of each. end being bent outwardly at right angles to rest on a part of a bed and the extremity of this part being bent upwardly to provide a stop for an edge portion of the spring assembly, links connecting the bars to the-spring assembly, each link being formed of two sections having their inner ends bent at right angles, the bent end of one section being pivoted to the other section an appreciable distance from the bent end of said other section, a stud on the bent end of said other section for engagement by the first section for limiting unfolding movement of the sections, and the outer end of the stud carry-- ing section being pivoted to a bar and the outer end of the other section being pivoted to the spring assembly.

4. In a structure of the class described, a stay device comprising a pair of links, the inner end of one link being directed laterally and provided with a stop element, with the corresponding end of the remaining link being directed laterally and pivotally attached to said first named link, the two laterally extending portions projecting in' substantially the same direction and the lateral part of said remaining link being pivoted to the other link an appreciable distance from the lateral part of said other link and the stop element being engaged by a part of said remaining link when the links are in unfolded position, and means for connecting the outer ends of the links with a bed frame and bed spring respectively.

5. In a structure of the class described, a stay device comprising a pair of links, the inner end of one link being directed laterally and provided with a stop element, With'the corresponding end of the remaining link being directed laterally and pivotally attached to said first named link, the two laterally extending portions projecting in substantially the same direction and the lateral part of said remaining link. being pivoted to the other link an appre-.

ciable distance from the lateral part of said other link and the stop element being engaged by a part of said remaining link when the links are in unfolded position, means for conheating the outer. ends of the links with a bed frame and bed spring respectively, and a spring connected atone end to one of said links and at the other end to the part of the bed to which said link is connected.
